Rugby fans flocked to Eason in Belfast tonight to meet one of Ireland's towering stars.

The 6ft 6ins Irish rugby legend, Paul O Connell was at the Donegall Place store on Sunday to sign copies of his autobiography 'The Battle', which details the highs and lows of his remarkable rugby career.

The former Ireland captain is synonymous with passion, heart and determination; but also has the reputation of being the thinking man's rugby player, a legendary student of the game.

As the heartbeat of Munster, British and Irish Lions captain in 2009, and captain of the first Ireland team to defend a Six Nations championship, O'Connell has emerged as perhaps the most beloved of the golden generation of Irish rugby players.

In a bumper weekend of sports stars, Eason welcomed John Kavanagh on Saturday to meet with fans and sign copies of his autobiography ‘Win or Learn’ in which he documents his long journey to success, from a bullied young boy to a renowned trainer and mentor to the world’s best fighters.

In Win or Learn, John Kavanagh tells his own remarkable life story - which is at the heart of the story of the extraordinary explosion of MMA in Ireland and globally. Employing the motto 'win or learn', Kavanagh has become a guru to young men and women seeking to master the arts of combat. As the trainer of the world's most charismatic male MMA champion, his gym has become a magnet for talented fighters from all over the world. Kavanagh's portrait of Conor McGregor - who he has seen in his lowest moments, as well as in his greatest triumphs, is a revelation.
